That's just what we do too, we set our default not based on hardware, but looking back at our Torque logs pre-migration and increasing from the 1GB per core then to 2GB/core with DefMemPerCPU=2048 (default is 1 CPU core too). If you want more you need to ask for it. The benefit of that is that for us is that as our current Intel clusters have minimums of 4GB/core and 16GB/core then if a lot of people can get away inside that limit then you can still fit larger jobs into the memory and cores left over.
